Installation Space

2.2

For ease of installing the SUN2000

on the mounting bracket, connecting

cables to the bottom of the

SUN2000, and maintaining the

SUN2000 in future, it is

recommended that the bottom

clearance be between 600 mm and

730 mm.

Position for saving a

security torx

wrench

•The M12x40 bolt assemblies are delivered with

the SUN2000. If the bolt assembly length does

not meet the installation requirements, prepare

M12 bolt assemblies by yourself and use them

together with the delivered M12 nuts.

•Before installing the mounting bracket, remove

the security Torx wrench from the mounting

bracket and save it for later use.

•This document introduces how to install the

SUN2000 on a support as an example. For

details about wall-mounted installation, see the

user manual.

1. Install the mounting bracket.

3. Adjust the installation positions of the handles, and install the SUN2000 on the mounting

bracket.

2. Unpack the inverter and move it to the specified position.

Handles are packed in a fitting bag and are not delivered with the SUN2000.

If outdoor copper-core cables are used, select copper wiring terminals. For details about the

requirements for cables and terminals of other materials, see the user manual.

a(S

is the conductor cross

output power cable.)

•

If you choose the

ground point on the

chassis shell for

connecting a PE

cable, prepare the PE

cable.

•

If you choose the

ground point in the

maintenance

compartment for

connecting a PE

cable, use a four-

core

AC output power

cable and do not have

to prepare a PE cable.

240 mm2

•Cable outer diameter:

24–66 mm (multi-

core); 14–35 mm

(single-core)

If you choose the ground

point in the maintenance

compartment for

connecting a PE cable,

use a four

-core cable.

Otherwise, use a three

core cable or three

single

-core cables.

•Cable outer diameter:

4–11 mm

When three

communications cables

connect to the signal

cable connector, the

outer diameter of the

cables should be 4

•Cable outer diameter:

15–18 mm

Note a: The value is valid only if the conductors of the PE cable and AC power cable use the same

material. If the materials are different, ensure that the conductor cross

-sectional area of the PE

cable produces a conductance equivalent to that of the area S/2

. The specifications of the PE cable

are subject to this table or calculated according to IEC 60364

-5-54.

Note b: You are advised to use a soft cable to prevent poor terminal contact due to the bending

stress of the cable

. The cable diameter must comply with local cable standards. The factors that

affect cable selection include the rated current, cable type, routing mode, ambient temperature, and

maximum expected line loss.

Installing the PE Cable

4.2

•It is recommended that the PE cable

be connected to a nearby PE point.

Connect the PE points of all

SUN2000s in the same PV array to

ensure equipotential connections to PE

cables.

•To enhance the corrosion resistance of

a ground terminal, you are advised to

apply silica gel or paint on it after

connecting the PE cable.

Opening the Maintenance Compartment Door

4.3

•Do not open the host panel of the SUN2000.

•Before opening the SUN2000 maintenance compartment door, turn off the downstream AC

output switch and three DC switches at the bottom.

•Do not open the maintenance compartment door in rainy or snowy days. If you must, take

protective measures to prevent rain or snow from entering the maintenance compartment.

•Do not leave unused screws in the maintenance compartment.

1. Loosen the screws on the maintenance

compartment door. 2. Open the maintenance compartment door

and adjust the support bar.

Crimping

module

(Optional) Replacing the Crimping Module

4.4

3. Remove the crimping modules that are bound in the maintenance compartment and save them

properly for future use.

If the AC output power cable has a single core, replace the crimping module.

For some models, a three-hole rubber plug is bound in the maintenance compartment. After

removing the rubber plug, save it properly for future use

(Optional) Installing the Solar Tracker Power Cable

4.6

1. A switch-disconnector-fuse or fuse-switch-disconnector with a voltage of no less than 800 V,

current of 16 A, and protection type of gM needs to be installed between the SUN2000 and the

tracker controller for protection.

2. The cable between the wiring terminal on the power cable and the switch-disconnector-fuse or

fuse-switch-disconnector should be less than or equal to 2.5 meters.

Removing the Rubber Rings from the Crimping Module

4.5

Use scissors to cut off the joints of the rubber rings to remove them. All rubber rings are removed in

the same way.
